The C3 myotome commonly includes certain neck muscles that help bend the neck forward. The C3 spinal nerve dermatome typically includes the skin over parts of the upper neck. ![]() These foramina are situated between two adjacent vertebrae.Įach spinal nerve receives sensation from specific areas of skin-its dermatome and controls specific groups of muscles-its myotome. Within each motion segment, spinal nerves exit the spinal cord through small bony openings on the left and right sides of the spinal canal called the intervertebral foramina. This disc provides cushioning and shock-absorbing functions to protect the vertebrae from grinding against each other during neck movements, while also allowing movement in all directions. Between each vertebral body, there is a disc made up of a thick fibrous outer ring (annulus fibrosus) with a gel-like core (nucleus pulposus). Watch Cervical Vertebrae Anatomy Animation These joints are synovial joints that contain articulating cartilage to help facilitate smooth gliding movements between adjacent vertebrae. The vertebrae in the C2-C5 motion segments are held together with ligaments and connected by paired facet joints running down the back of the spine. Vertebrae and joints from C2 through C5.The C2-C5 motion segments include the following structures: See All About the C5-C6 Spinal Motion Segment and All About the C6-C7 Spinal Motion SegmentĪnatomy of the C2-C5 Spinal Motion Segments However, the C2-C5 motion segments are also susceptible to injury and can cause pain due to degeneration, disc herniation, trauma, and neurological injury. The lower cervical spine (C5-C7) is typically injured more often compared to C2-C5. Cervical motion segment percent contributions to flexion-extension during continuous functional movement in control subjects and arthrodesis patients. C4-C5 is typically more mobile compared to other motion segments between C2-C5.ġ Anderst WJ, Donaldson WF 3rd, Lee JY, Kang JD. The C2-C5 motion segments contribute the most to the mid-range of motion during the neck’s forward and/or backward movements. This group of motion segments starts with the C2 vertebra near the top of the cervical spine and ends in the mid-cervical spine at the C5 vertebra. Your lower back and neck should both curve away from the wall, and the back of your head should gently touch as well.The C2-C5 spinal motion segments comprise three individual segments: C2-C3, C3-C4, and C4-C5. If you are still unsure, place your head and back against a wall and try to find the position that allows most of your upper back and hips to be aligned on the wall. Your proper relaxed posture of your shoulders is reached when you pull up, push them all the way back and then drop them into a relaxed position. Your chin should be parallel to the shore, and not downcast when you walk. If you are unsure, have others take a picture of your neck, shoulder and head posture. One of the biggest ways to help and prevent additional injury to your neck, C5 and C6 vertebrae is to work on your posture. Repeat on both sides of the head and the back of the head as well. Place your hand on your forehead and press, pushing back to keep your head upright. Sit up straight and use your hand to push against your head. Resistance can be done simply with your hand and a straight-backed chair. The neck already holds up your head, and bears weight constantly. Once you feel sufficiently loose, you can begin your exercises. Hold your arms limp, and rotate your torso so that your arms swing gently back and forth. Make large circles with your arms as well, to stretch the shoulders at the base of the neck. Only go until you feel pain, don't try to push past it. ![]() Rotate your head in circles, toward the front, back and both shoulders. This can help health insurance to cover the cost instead of you footing the entire bill.īefore doing any kind of exercises involving the neck, it's a good idea to stretch the area. If you are worried about the cost of massage, consider getting a prescription from your doctor for treatment. Pressure point massage and heat applications can do a lot to break down some of the tissue that is holding the neck in an improper position. Physical therapy can be done with neck and shoulder strengthening exercises, but the risk of injury if you are not careful is high, so a number of precautions should be taken. Osteoporosis, spinal compression and cervical disk degeneration are all things that many find will come with age, and which can complicate cervical issues further. Neck position, hunching and bad sleep can all create a buildup of fascial tissue that holds the spine in a bad position. The C5 and C6 cervical vertebrae are the lowest neck vertebrae that lead into the shoulders.
